Abstract
For the first time, we report the thermal conductivity of vertically aligned boron nitride nanotube (BNNT) films produced by catalytic chemical vapor deposition. High-quality BNNTs were synthesized at 1200 °C on fused silica substrates precoated with Pt thin-film thermometers. The thermal conductivity of the BNNTs was measured at room temperature by using a pulsed photothermal technique. The apparent thermal conductivity of the BNNT coatings increased from 55 to 170Wm-1K-1 when the thickness increased from 10 to 28 μm, while the thermal conductivity attained a value as high as 2400Wm-1K-1. These results suggested that BNNTs, which are highly thermally conductive, but electrically insulating, are promising materials with unique properties.
